Patentedy oct. 11, 193s i UNITED STATE PORTABLE REWINDING MACHINEyOsborne I. Price, Frederick, Md. ,l y Application June 25, wssgserialNo. :57,303Y solaires. (c1. 242-1) f f My invention relates broadly toline-throwing equipment and moreparticularly to a portable rewindingmachine for rewinding lines after they v have been projected.

v One of the objects of myinvention is to pro-y vide a construction ofportable krewinding machine for lines, which is simple in itsconstruction and relatively light in weightand vwhich is adapted toquckly rewind a line after it has `been projected. A Q

Another object of my invention vis to provide a construction of`rewinding machine for lines having means for accurately guiding the lineupon the storage spindle in 'ai rewinding process 4for insuring thequick return of the line to the spindle, with minimum entanglement-.ofthe line.

Still another object of my invention is to provide a construction oftensioning meansfor uniformly guiding a line vupon the storagespindle ofa portable rewinding machinefor insuring quick restoration ofthe linetothe spindle in uniformly tight loops about the spindle.

A further object of my invention is to provide a' construction of cammechanism,` operative through a reduction'gear for controlling thereciprocatory travel of a line guide with respect to the linestoragespindle.

A still further object of my invention is to prol vide an arrangement ofrackand pinion system,

interposed between the reciprocatory cam control mechanism and the' lineguide in a rewinding machine for predetermining the rate oftravel of theline guide withv respect to the rotation 'of the lineV storage spindle.f

StillY another object of my invention `resides in the construction oflight, compact Aand portable line rewinding machine, which may bereadily moved into position upon the deck of a ship, for` rewinding aprojected line, and suitably housed for'protection of the moving partsagainst the elements. 1

After the line has been used, the line may bel subject to entanglementand knotting. However, with the machine of my invention, the line may bequickly rewound so as `to be ready for instantY use for thenext shot.The rewinding apparatus of my invention is readily portable and isextremely light in weight so that the apparatus r may be shiftedrto anydesired position for use on the deck of a vessel or in places Wherespace is limited. The mechanism is extremely simple so that themanufacture of the apparatus is inexpensive and there are but few partsto be replaced because of wear. I provide several different forms of myinvention and for the 'pur' pose ofillustration, Ihave shown two oflthese forms. One form of the inventionY comprises a small lightweightmachine capableof rewinding a rope of relatively small size of a lengthof from 500to Y"IOOifeet rwithin a very short time. In the largersize'rewinding machineillustrated herein,

the rewin'ciing mandrel or spindle will accommo-` date a much heavierrope of much greater length.

Because of the diiference in sizeof the ropeV adapted to be rewound bythe diiferent machines, the larger size machines are equippedfwith adriving gear for` the rope guide adapted. to drive the rope guide agreaterdistance and at a dif.

ferent rate thanis the casewith the rope. guide in the smaller sizemachine. Forthis purpose, I provide a gear rack and pinion systeminterposed between the reciprocatory mechanism which carries the ropeguideVV and the ropev guide immediatelyadjacent the coil 'of rope onVthe spindle.4V The reciprocatory mechanism includes a 'cardioidY shapedcam adapted to reciprocate the guide mechanism adjacent the spindle onwhich the rope is coiled. The'spindle includesspecial'means forretaining the rope in .position'thereon and special means fortensioningthe rope` as'it is guided upon the coil carried bythe spindle.For handling different Vsize ropeg'I provide different kinds oftensioning means. For the smaller rope, I may provide guide andtensioning means which are very'compact.' For the larger size rope, Iprovide Ytensioning and4 guide 'means adjustable in position and adaptedto guide the rope in proper tensionupon the coil.Y

Referring to the drawings indetail, reference character I indicates thebase of`one form Aof the rewinding machine of my invention.` The base I'is pressed from. sheet metal and'is supported by the metallic anglemembers 2 lforming supporting feet.Y There is an aperture 3 in onecorner of the base which servest receive theV storage 'roller in'removing the coil therefrom' when it is desired to'take off the coiledrope which has been received on the storage Vrolleror mandrei'. Iprovide a c'over'l which serves to protect Ythe rewinding equipment fromthe elements. andthe weather andthe sea. The cover 4 provides anenclosure' which is'hinged at 5 by means of hinges secured'lto the VbaseI through means indicated at 5a. Ahasp I5v is secured to the base I andis adapted to Vbe looped over the hook 8 on the 'cover 4.Y 'A suitablecatch I is adapted to be latched through'the loop 8 in order 4tomaintainA the cover 4 'in position. A handle@ is arranged'for carryingthe rewinding equipment. The base I carries'fa' standard Il]- adjacentone end thereof and a triple standard I I adjacent the other endthereof'as shown. There is a central vertical bearing extending throughthe triple standard II as shown at I2 and in the bearing I 2, there isjournaled a vertical shaft I4.

The vertical shaft I4 carries a bevel gear I5 at the upper extremitythereof secured by any suitable means such as set screw I5 whereby thebeveled gear I5 is adapted to be moved in unison with'the shaft I4. Thatis to say, by driving gear I5, rotary motion is imparted to the centralshaft I4. There is a keyway I'I which is adapted =to ibe aligned with akeyway I 8 formed in the hub I9 of the cardioid shaped cam indicated at20.- The hub I9 of the cardioid shaped cam 20 is Yadapted to be` securedto shaft I4 by suitable means such asset screw 2| which coacts with akey which fits between the keyways I'I and I8 for positively locking thecardioid shaped cam 20 with respect to the rotatable shaft I4. Thecardioid shapedcam shown at 20 is adapted to drive a cam drivericarwhich I have indicated atV 23 through the Vagency of a pair of camfollowers or rollers indicated at 22. There is alongitudinallylextending 'central slot 24 in the camdriven car 23through which the shaft I4 and the surrounding hub I9 of the cardioidshaped camY 20"extends.AV I provide a pair of laligned U- shaped tracks25 which are secured to the under side of the base I and have their sidefianges depending'downwardly 'to provide a pair of rail guides for theVrollers 26 and the upper side of the cam driven car-23. That is to say,the rollers 26 engage' within the U shaped tracks 25 so thatV the camdriven car 23 is adapted to be reciprocated'longitudinally of the base Ias the cam 20 rotates and engages the cam follower rollers 22. It-willbe observed that one of the rollers 25 is directly above one of theVdepending rollers 22 driven by the cardioid shaped cam 20. The otherroller 26 'is-located adjacent the opposite end of the Ycam driven car23 and serves to maintain the cam .driven car in a predetermined pathasV the cardioid shaped cam 20 rotates. In order to assure the'precision movement of the cam driven car 23, I provide a pair cftrack'members on opposite sides of the'cam driven car 23. A relativelylong track memberis shown at 21 which is a substantially ZV type trackfor the line guide carriage at the long side of the line guide carriage.I provide aV relatively shorter track 28 of the same ZV type section forthe shorter side of theV line guide carriage;Y The rails 21 and 28 aresecured tothe base I by suitable means such as securing screws withattached nuts indicated at 21a and 28a' passing through the base lI forsecuring'the rails 2l and-28 tothe under side of the basev I. Thecarriage 23 is provided with rollersZS` on the longerside'thereofengaging railY 2'I VandV rollerV 30 on the opposite'sidethereof engaging rail 28. f The line guide which is reciprocated by theline guide carriage 33 is driven by suitable 'attachment'mean'sindicated at 3I which extend through the base I passing through thelongitudinally extending slot shown at 32.

The slot 32 extends along base I for the entire length of thereciprocating path of the line guide which I have'shown at 33. The lineguide 33 will be more clearly understood by reference to FigsSZ,3,"and10-14. Line guide carriage 33 carries Yextension lugs' 33a.thereon which are adapted to` be engaged with respect to the upwardlyextending attachment means 3I projecting upwardlyrthrough base I fromthe line guide carriage 33. "The extension means 33a connect aiscgocs'projecting laterally therefrom and'on which the' line tensioning device35 is mounted. The line tensioningdevice 35 is made up of two coactingmembersY 35a and 35h which are pressed into continuous engagement toform a pulley around whichl the line is directed. The parts 35a and 35hare pressed into engagement by the soil spring 36, the tension on whichis adjusted by means of adjustable screw 31 engaging screw threads onthe stud 34. The line guide 33 also carries an eye 38 for guiding theline before it enters, and an eye 39 for guiding the line after itleaves the tensioning'pulley 35. There is a line guide slot 4I! in .theline guide carriage 33. A packing roller engaging means' and line guideshown at 4l is carried bythe upper extremity of the line guide carriage33 for continuously guiding the line and engaging the line on the linestorage roller during the operation of the rewinding mechanism.

t The lline storage roller is shown at 42 and as illustrated moreparticularly in Fig. 18, there is t an end slot 42e therein in which theendof the rope may be engaged before the coiling operationV iscommenced. The line storage roller 42 Vhas the vopposite ends thereofrecessed as shown more particularly in Fig. 16 from which it will beseen that there is an endrecess 42a in one end and a slot and recessV42h in the other end of the roller 42. It will be observed that recess42a is substantially clindrical whereas recess 42D is substantiallyvcylindrical with a radially extending slot on either side for engagementby the driving spindle head shown Aat 41. TheY standard I@ as shown moreparticularly in Figs. 15 and 16 carries a locking head 43 thereon whichincludes a locking slot 44 and a semicircular recess 45. A winding key45 extends through the axial bore through the locking head 43. Thewinding key 4B includes a handle grip shown at 46c and illustrated moreparticularly in Fig. 20, anda pin 46h substantially midway of the`length thereofl and an end flange 46c which allows the end of thewinding key to extend into the recess 42d in the'storage roller 42. l

` As heretofore pointed out, the driving spindle head 41 engages theslot 42h in storage roller 41 for driving the storage roller 42 aboutthe recess 42a and the projecting end of the winding key 46 asillustrated in Fig. 16. The driving spindle head 41 is operated by thedriving spindle shaft Shown at 48. The driving spindle shaft 43 ismounted in journals 49 and 5I! in the triple standard Il. There is a pin42a in the end of driving spindle shaft 48 which is adapted to beengaged with the socket of a driving crank 52. The socket of the drivingcrank 52 is slotted as indicated at 53 for vengaging the ends of the pin48a and Vallowing the driving spindle shaft to be rotated to impartrotary movement to the driving spindlehead 41 for correspondinglydriving 3I and laterally with respect to the -ing shaft and isv adaptedto mesh with the bevel gear l5 heretofore described. Rotary motionimparted to crank 52 is accordingly transmitted both to the line'storageroller 42 and to the cardioid 'shaped cam 2d which in turn moves the camdriven car 23' through cam followers 22 for imparting movement to theline guide carriage 33 which in turn feeds the rope or line 56 upon themandrel orlinel storage roller 42. The movement of the lineV guidecarriage 33 is originally set so that the line guide carriagereciprocates as the line is fed from one end of the coil to the otherend thereof. The coil is built up on the line storage roller 42 in theshape illustrated more particularly inv Figs. 21 and 22. The line isrewound rapidly vupon the storage roller 42. It may be desirable toremove the coil 51 from the storage roller 42 in which event the storageroller is projected through the aperture 3 in base I as illustrated inFig. 21 with the end of the coil 51 restheavier line must be handled andin such cases l provide a larger and heavier construction of rewindingmachine. As illustrative of the larger `machine, reference is made toFigs.`2333.

`The base of the larger machine is indicated at 60 mounted upon suitablechannel beams which greatly strengthen the base structure.V Theconstruction ofthe large size rewinding machine is with two majorexceptionssubstantially the same as that of the smaller rewindingmachine. The two machines have different constructions of line guides.In the larger machine, there is a multi-- plied drive for the line guidecarriage. This multiplieddriv'e makes it possible to use the same sizecam in the `large machine as is used in the smaller machine to obtainthe much longer axial length'of winding Vrequired on the larger sizemachine. 'I'hat is to say, the same tools maybe employed forconstructing thereciprocatory driving mechanism in both machines and yeta sturdier and a longer path drive obtained in the larger sizemachine bymeans of the mechanism hereinafter explained.

I provide a standard 6I adjacent one end of the base 62. There is'abearing 62 in the head of the standard 6I throughV which the winding key63 extends. The winding key 63 as shown' more particularly in Fig. 24has a flange 63C thereon which limits the distance into which the end ofthe winding key projects into the recess 64a in the end of the Vlinestorage roller 64. The recess 64a is substantially cylindrical in shapeand receives the end of thel winding key 63.

'Ihe driving head 65 which imparts movement to the mandrel or spindle 64is driven by the driving spindle shaft shown at 1I which is journaled insubstantially the same manner as is the driving spindle shaft 48 in theform of my invention heretofore described. In the larger ysize machine,however, the supporting parts and bearings are substantially larger andmore rugged. I have shown. at 12 the triple standard which providesbearings 13 and 14 for the driving spindle shaft 1I. The shaft 1I isdriven through the crank 15 which may be connected with the drivingspindle shaft 1I when required. The central -portion of the standard 'I2provides a bearing for the central shaft which is the equivalent ofshaft I4 in the earlier form of myfinvention and in the modied formthereof. The shaft I4 carries the bevel gear I5V which meshes with theVcating cam driven car has been shown at 85' mounted in much the samemanner as the car 23 in the previous form of my invention. The car 68 isprovided with a pair of follower rollers 22 which engage the cam 20 andallow the reciprocatory car 68 to be shifted back and forth. On theupper surface of the car 68, I mount rollers 26 which engage thedepending channel shaped members 25 in order to guide the cam driven carin its reciprocatory path. Because of the heavy construction of' car 96,I increase the number of guide rollers 29 as indicated in the drawingsin this form of my invention. The sidewalls of the car 88 are bentupwardly vand serve to carry the roller members 91 and 68. The rollermembers 67 and 88 operate in the Z shaped rails 89 and le secured to theunder side of the base support shown at 68. The cam driven car 66 isthus free to be driven in a reciprocatory path back and forth in orderto operate the rope guide means as hereinafter more fully described.

rihe cam driven car 86 carries a rack member l? on one side thereof asshown more clearly in Fig. 26. The rack "Il engages a pinion 18 carriedon the same hub or shaft as is the larger gear 'i9 which is drivensimultaneously with the movement of the pinion 78. The pinion 'i8 andgear "I9 are mounted on a hub which is journaled or ivoted about ,a stubshaft 80 which is carried by 1 the frame 8i serving as a journal fortheshaft 80.

The gear 'I9 meshes with an extended rack 83 which connects at one endwith the drive 82 for the line guide carriage. The rack 83 is maintainedin engagement with the gear 'I9 by the action of roller 88 operatingagainsttthe rear of rack 83 as the rack 83 reciprocates. The drive S2for the line guide carriage is operated in a reciprocatory path undercontrol of the guide rails 86 and 8l secured to the frame structure 99.`

Thedrive 82 carries a set of rollers 84 and 85 which engage the guiderails 86'and 8'! for allowing the guide 82 to be driven in areciprocatory path. VThere is a slot 90 in the base structure tifsthrough which lugs 9| on the driver82 project. 'I'he lugs 9| areapertured at 9|a to allow a pin 92 to extend therethrough and serve as aconnecting means for the lugs 94 on the'body of the line guide carriageV93 shown more particularly in Figs. Y28 and 29.

The line guide-carriage 93 is provided with a tension spring adjustingscrew shown at 96. The screw 99 is provided with a swivel head 91whichbears against the roller of the line guide carriage 93 and allowsthe member 96 to rock to various angular positions in order that thebody structure 9S of the line tensioning device may shift to variouspositions. The member 96 is provided with a tension spring 99 whichbears against the body structure 98 of the line tension-ing device. Anadjusting screw is adaptedto be'adjusted with respect to spring 99 forpredetermining the Aspring pressure exerted against the body structure98 and accordingly mandrel or spindle 64., Ihe line guide carriageVroller shown at I I2.

which I have designated by aVV similar numberi 93 is provided withVoutstandingA lug members ISI adjacent the top thereof which serve as ahinge for the body structure 98 of the line tensioning device. A pin |02extends through the body structure 98 and the lugs I0| for hingedlysupporting the body structure 9B with respect to the line guide carriage93. The line guide carriage 93 is also provided' with-'rearwardlyextending lugs Vor projections |04 which serve as a pivot means for theline tracking The line tracking roller I I2 is secured between theprojection members |04 by means of the removable line tracking rollerspindle |05.

The line guide carriage 93 carries a line guide member and a pair ofline guide members Iii'i for directing the line |88 under the first ofthe guide rollers |93. The line extends between the guide rollers shownat |03. That is to say, the line |89 extends'under the lower roller |03and over the upper roller |83 carried by the bodyV structure '98 of theline tensioning device and then extends underA the line tracking roller||2 from which the line is distributed to the coil shown at |09. Therope is rewound on the mandrel or spindle Yell into a coil |09 in thesame manner as heretofore described'. When the rope is rewound on themandrel or spindle, it may be removed as a complete coil asheretofore-described in connection with Fig. 21 and Fig. 22. It will beobserved that the line tracking roller 52 is relatively wide. There isno central groove in the line tracking roller I2 soV that the rope isermitted to change in Vits angular position as the rope is supplied tothe coil on the mandrel or spindle. That is tosay, the rope may assumevarious angular positions as the rewinding voperation proceeds. Therewinding isY generally conducted at relatively high speeds and it ispossible to restore the mandrel within a very brief interval even whenthe rope-is of very long length such as lengths of 2100 feet. I haveaccomplished such rewinding of relatively heavy rope of Vlengths, of2100 feet in such intervals of time as seven minutes which is anaccomplishment which greatly facilitates the use of the rewindingapparatus with line Ythrowing equipment in lifesaving operations.

As in the earlier form of my construction, I`

provide a protective plate beneath the moving mechanism. I have shownthe plate atr IIO secured by suitable means I I I to the under surfaceof the supporting frame 60.

The tandem multiplying gears 'F8-I9 are arranged one above the other ona common hub. The smaller of these twogears, that is, '18, engages theshort rack 'il attached to the cam driven car (5E. The larger gear 19engages the long rack 83 attached to the line guide carriage 93. Thethrow ofthe cam is transmitted to the multiplying gears by the shortgear rack The throw of the cam is multiplied and reversed in these gearsas the motion is transmitted to the long gear rack 83 and line-guidecarriage 93. The multiplying factor of these gears is equal to the ratioof the larger to the smaller of their pitch diameters.

By virtue of the ilat construction of the cardioid shaped cam 20 and thecompactness of the parts associated therewith, the base of the machineis of relatively low height. The operation of the reciprocatorymechanism is such that for continuous driving of the storage roller,reciprocation ofthe line guide is effected, automatically reversing asthe end of the coil is reached.

I intend no limitations upon my invention other than may be imposed bythe scope of lthe appended claims.
